DTC P0617 Starter Relay Circuit High


DESCRIPTION

While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM.
If the ECM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores the DTC.
This monitor runs when the vehicle has been driven at 20 km/h (12.5 mph) or more for more than 20 seconds.

INSPECTION PROCEDURE

NOTICE:
  1. Inspect the fuses of circuits related to this system before performing the following inspection procedure.
  2. After replacing the ECM, the new ECM needs registration (LandCruiser RM0000012XK0AUX.html) and initialization (LandCruiser RM000000TIN08HX.html).
HINT:
  1. The following troubleshooting process is based on the premise that the engine can crank normally. If the engine does not crank, proceed to Problem Symptoms Table (LandCruiser RM0000012WF0AEX.html).
  2. If this DTC is output, inspect the starter assembly.
  3. Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
1.READ VALUE USING GTS (STARTER SIGNAL)

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG) and turn the GTS on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.

  1. Read the value displayed on the GTS when the vehicle is driven at 20 km/h (12.4 mph) or more with engine speed at 1000 rpm or more.

    Result:

CHECK FOR INTERMITTENT PROBLEMS (LandCruiser RM000000PDQ19IX.html)

2.INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

  1. Inspect the park/neutral position switch assembly (LandCruiser RM000000OD401HX.html).



NG
REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY (LandCruiser RM000000O5O01MX.html)
OK


3.REPAIR OR REPLACE HARNESS OR CONNECTOR (STA SIGNAL CIRCUIT)

  1. Repair or replace the harness or connector (STA signal circuit).



NEXT
Go to step 6

4.INSPECT CLUTCH START SWITCH ASSEMBLY

  1. Inspect the clutch start switch assembly (LandCruiser RM0000032S300DX_01_0001.html).



NG
REPLACE CLUTCH START SWITCH ASSEMBLY (LandCruiser RM00000176C00OX.html)
OK


5.REPAIR OR REPLACE HARNESS OR CONNECTOR (STA SIGNAL CIRCUIT)

  1. Repair or replace the harness or connector (STA signal circuit).

6.CHECK WHETHER DTC OUTPUT RECURS (DTC P0617)

  1. Connect the GTS to the DLC3.

  1. Clear the DTCs (LandCruiser RM000000PDK1E5X.html).

  1. Turn the engine switch off and wait for at least 30 seconds.

  1. Turn the engine switch on (IG) and turn the GTS on.

  1. Drive the vehicle for 25 seconds or more at a speed of 20 km/h (12.5 mph) or more and an engine speed of 1000 rpm or more.

  1. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

  1. Read the DTCs.

    Result:
